hard to tune heated chamber PID

Hi. Im really having a hard work at tunning the PID of the heated chamber. I ha ve a powerfull heater but I get always to -5 degrees of my target temperature. Documentation says that if I undershoot I should increase R (firmware 3.3).
My PID settings now are:
M307 H0 R0.12 C284.700:284.700 D30 S1.00 V0 B0
the R value is at 0.12 now and I get those -5 degrees of target temperature. Previously was at 0.05 and the undershoot was still -5 degrees, shoud, I keep increasing this value till I get target temperature? in bang bang mode I have no problem on reaching the target but the oscillations goes from +- 10 degrees. It is too much so I would like to have PID working
Thanks in advance
